holy_calamity writes: When Microsoft re-engineered its online services to assist NSA surveillance programs, the company was either acting voluntarily, or under a new kind of court order, reports MIT Technology Review. Existing laws were believed to shelter companies from being forced to modify their systems to aid surveillance, but experts say the Foreign Intelligence Surveillance Court may now have a new interpretation. Microsoft's statement about its cooperation with NSA surveillance doesn't make it clear whether it acted under legal duress, or simply decided that to helping out voluntarily was in its best interest.
